To perform a factory reset, go to the settings menu, select 'System', and then 'Reset'. Choose 'Factory Reset' and confirm your selection. This will restore the TV to its original settings.
Check the connection of all video cables and ensure they are securely connected. Adjust the picture settings in the TV menu, such as brightness, contrast, and sharpness. If the issue persists, try a different input source.
On the TV, open the settings menu, select 'Network', and then 'Wi-Fi Setup'. Choose your Wi-Fi network from the list and enter the password. Ensure the TV is within range of the router.
Yes, you can connect a streaming device via one of the HDMI ports on the TV. After connecting, switch to the corresponding HDMI input using the TV remote to access the streaming device interface.
